Rearrange 'make getstubs' slightly, so that we do not require the stub files present in generic/* for the build machinery to work properly

nsf.c: - make types for bit operations unsigned (mostly flags)

  1. … 7 more files in changeset.
nsf.c: - implement a new approach to error reporting in ensembles: instead of trying to find the "right" place to report the best "error", compute the longest valid ensemble prefix from all the stack frames.

small introspection reform: - Introspection for commands and arguments did not work for cmds defined in subpackages (such as mongodb). We keep now this information in hashtables and maintain a slim interface for this. - fix generation of pkgIndex.tcl for mongodb

Version generated for Tcl 8.5 - maybe we keep this out from the repo in the future

- Adding support for "cls|obj info method returns" - generic/nsf.c: ListMethod() now handles a InfomethodsubcmdReturnsIdx subcmd. - generic/nsfAPI.decls|nsfAPI.h|nsfDecls.h: Registerung a new "info method" subcmd: "returns"

- nsf.c: * enabled MEM_COUNT debugging for multi-threaded apps. We collect the MEM_COUNT statistics now per interp. Therefore, we have to pass around "interp" in case where alloc() and free() or refCount functions are used (textually, a big change) * verified, that nsf runs clean in aolserver/naviserver (all INCR_REF_COUNTS all balanced)

- nsf.c: * fixing compliation with NSF_MEM_COUNT * New function DeleteProcsAndVars() to trigger deletion of ParamDefs (fixes a small mmemory leak); * improved comments

- nsfStack.c / CallStackMethodPath(): Providing a fix for reporting method paths correctly when dispatching to ensembles from alias parameters. Prior to that fix, the intermediate (and inactive) CMETHOD frame wrapping configure() calls caused [current methodpath]s to report empty string elements. Added some test cases. - nsf.c / ObjectDispatch(), DispatchUnknownMethod(): When testing objects as alias parameter targets, I found cases when the default (C-level) unknown handler was invoked upon. The result was an unknown message which reported the delegator object as "unknown" method! This was due to injecting the delegator object into the argument vector at position 0, subsequently used by the C-level unknown handler. First, I tried to make the C-level unknown handler aware of the ensemble call context (by funneling through the CSC and frame flags) but this turned out to be complicated to achieve this simple task. As an alternative, I suggest the following patch: The first argument in unknown calls is treated as a list, and dependening on the call context (ensemble vs. non-ensemble) contains all the necessary call data. For ensemble methods, it is the delegator object, the entire method path (as returned by [current methodpath]), and the actual unknown selector. The default C-level handler, treating the call info as list, resorts to reporting the last element of the list which is always the unknown selector. Custom (ensemble-level, application-level) unknown handler can wrap and further process the information as necessary. To demonstrate the usefulness, I rewrote EnsembleObject->unknown() accordingly. I checked for Tcl_Obj leaks. - Added some tests on objects as targets of alias object parameter. To be continued.

- nsf.c: * improved source code documentation * added parameter option "args" in order to get eventually rid of hard-wired residual args. * improved a few error messages * fixed object parameters consisting only of plain parameters (previously, no parameters were returned in this case, e.g. for method parameters; but object parameter code depends on it) - extended and updated regression tests

- remove unneeded var when compiled without profile support

* added profiling support for nsf::proc when NSF_INVOKE_SHADOWED_TRADITIONAL is turned off.

  1. … 4 more files in changeset.
- nsf.c: * added a new converter for converting mixins with guards (named mixinspec) * used mixinspec in nx.tcl and xotcl2.tcl * extended nx regression test.

- added gentstubs built with 8.5.9

- removed unneded functions: NsfComputePrecedence(), NsfComputeDependents(), Nsf_SetVar2Ex(), NsfOSetInstVar(), Nsf_ObjGetVar2(), NsfOGetInstVar(), qNsfCreateObject() - removed unneeded external declarations: NsfClassListAdd() NsfClassListFree() - make extern declarations explicit - grouped most extern definitions together - improved documentation - moved variable declarations to inner scopes - removed warning from cppcheck()

  1. … 9 more files in changeset.
- added experimental ::nsf::proc for realization of procs with next scripting argument passing. These nsf::procs improve the orthogonality of the code (using e.g. nonpos args and value checker for procs) and allows the same introspection interface (info method parameter|parametersyntax, ...)

  1. … 6 more files in changeset.
- streamlined error messages - removed NsfErrBadVal() and replaced it with a generalized version of NsfObjErrType(

  1. … 7 more files in changeset.
- made error messages more consistent - improved error messages for "returns" and "nsf::is" (omit parameter name)

  1. … 11 more files in changeset.
- further cleanup of error procs: eliminated NsfObjErrArgCnt() - improve error message, when too many arguments are passed

  1. … 8 more files in changeset.
- new printf-style error message generator: NsfPrintError() - simplified error handling: removed NsfVarErrMsg() and NsfErrMsg() and replaced it by NsfPrintError()

  1. … 9 more files in changeset.
- quote name of referenced parameter in error message to ease reading - new parameter checker "parameter", performing an approximate checking for valid parameter specs - set NSF_ARG_CHECK_NONPOS only when there are multiple arguments - remove space checking for NSF_ARG_CHECK_NONPOS in favor of parameter checker

  1. … 11 more files in changeset.
- provide a generic logging interface * predefined for plain Tcl and aolserver/naviserver * C-level: NsfLog() * Tcl-level: ::nsf::log
